IGEARING lfO'R WASHING MACHINES.

application'filed July 10, 1920. Serial no. 395,235.

First, to provide an improved gearing for washing machines. I

Second, to provide in a washing machine 'an improved gearing whereby the cylinder of the oscillating type is oscillated throu h I a long stroke, the mechanism being simp e,

strong and durable.

Third, to provide an improved gearing for washing machines which is substantially noiseless and reverses the oscillating cylinder with a minimum of shock to the gear- I Fourth, to provide an improved gearing for washing machines which is assembled and supported on a frame so that it may be installed as a unit within the main frame of a washing machine.

Further objects, and objects relating to structural details will definitely appear from the detailed description to follow.

We accomplish the objects of our invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.'

A structure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Fig. I is a perspective view of awashing machine embodying the features of our in vention.

Fig 11 is an end view looking from the right of Fig. I, with the door of the gearing housing open, the door being partially broken away.

Fig; III is a detail horizontal section on a line corresponding to line 3-3 of Figs. II and IV.

Fig. IV is a detail vertical section on a line corresponding to line 4r4.- of Figs. II and III.

Fig. V is a detail horizontal section on a line corresponding to line 5-5 of Fig. II,

Fig. VI is a detail view partially in vertical section on a line corresponding to line 66 of Fig. II.

Fig. VII is a detail section through the gear box on a line corresponding to line 77 of Figs. II and VI.

Fig. VIII is a detail section on a line cor responding to line 88 of Figs. II and VI, showing details of the wringer mechanism.

In the drawing similar references characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, we provide a main frame consisting of front corner uprights 1 and rear corner uprights 2 connected by top and bottom horizontal pieces 3 and 4, the bottom horizontal piece 4 at the right hand end being omitted. We provide a rear panel 5, front panel 6 and end panel 7 for the left end and a door 8 for the right end of the casing, the door being hinged at 9' to the rear corner upright as shown in Fig. I.

The tank or receptacle 10 is mounted within this casing in a spaced relation to the door 8 to provide a housing 11 for the gear supporting frame and gearing, the gearing being exposed when the door 8 is open. The casing is provided with a re-' movable cover 12.

v The washing cylinder 13, parts only of" i which are shown, is provided with journals l4: removably supported by the bearings 15 and 15' projecting within the receptacle so provided with outwardly projecting arms 20 at its front end bolted to one of the front uprights with an arm 21 at its rear upper corner bolted to the rear upright, and the gear box 22 at its lower rear corner bolted to the rear upright so that this gear supporting frame not only constitutes a supporting means for the gearing, but also serves as a frame member bracing the end of The driven shaft 17 is provided with a driven gear 23. A rack 24 coacts with this gear, the rack being supported in a substantially upright position to mesh with the gear by means of the roller 25 mounted on the stub shaft 26 onthe frame 19see Fi s. II and III. The rack is driven from t e driving wheel 27 mounted on the stub shaft 28 on the inner wall of the gear box which projects above the outer wall. The driving wheel 27 is provided with a crank pin 29 and meshes with a worm 30 on the driving shaft 31 which is arranged in bearings 32 and .33 in the gear box 22. One end of this shaft v31 rojects through the bearing'33 and is providled with a pulle 34 driven from the motor 35 mounted be ow the receptacle 10.

The supporting roller 25 is grooved to receive the rack 24 thereby supporting the rack against lateral movement. The gear 7 23 is shifted laterally of the rack when the shaft 17 is shifted to engage and disengage the clutch members 16 and 18, the clutch members being shown disengaged in Fig. III.- The shaft 17 is shifted by means of the eccentric 36 which has a pin 37 engaging the groove 38 in the shaft, the eccentric being rotated by the rod 39 provided with a hand piece 40 at its upper end. A detent ball 40 is provided for the eccentric 3 6.

The wringer designated generally by the numeral 41 is mounted on the tubular bracket 42 projecting horizontally from the spherical reverse gear box 43. The gear box 43 is provided with a tubular support 44 supported in a bearing 45 on the gearing frame 19 so that the gear box 43 may be rotated in this bearing to swing the wringer to the different positions desired in use. The wringer shaft 46 is connected by the couplln'g 47 to the reverse gear shaft 48 within the gear box 43, the wringer shaft being Zrranged in the tubular support or bracket The reverse gear shaft 48 is provided with a pair of oppositely facin beveled gears 49 coacting with the bevele gear 50 on the shaft 51 in the support 44. A couplin 52 is provided at the bearing 45 for the s aft 51 to the driven shaft 53 so that if desired, the reverse gear box with the parts mounted thereon may be lifted from the frame. The shaft 53 is provided with a gear 54 meshing wlth the worm 55 on the shaft 31.

Thus sup orted the wringer may be swung around as esired and it is secured in any desired position by means of the clamp 56 which embraces the support 44, the clamp being provided with a slot at 57 through which the clamping screw 58 is arranged, the clamping screw being provided with a hand piece 59 on its outer end.

To reverse the driveof the wringer, we provide a clutch member 60 splined to the shaft 48 to coact with either of the clutch members 61 on the reversing gears 49. The clutch member 60 is shifted by means of the rocker 62 arranged through the top of the gear box 43 and provided with a hand piece 63. The details of the'clutch are not illustrated as suitable clutch means are well known. The clutch member is arranged so that it may be-adjusted to a central or neutral position and the wringer ma be driven with the washing cylinder or in ependently thereof.

With this arrangement of parts, the gearing is enclosed so that the operator is not likely to be injured thereby. At the same time, it is fully accessible. The gear box 22 constitutes a lubricant receptacle so that most of the parts requiring lubrication are effectively lubricated therefrom and the lubricant does not drip on the floor.

Our improved gearing is very quiet in its operation. The gearing is supported on a rigid frame so that it does not get out of alignment and the wear thereon is minimized.

We have illustrated our improvements in a commercial embodiment. We have not attempted to illustrate or describe other modifications which we contemplate as we believe the disclosure made will enable those skilled in the art to which our invention relates to embody or adapt the same as may be desired.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In a structure of the class described, the combination of a rotatable element having a journal provided with a clutch mem her, a bearing in which said journal is re movablyarranged, .a driven shaft slidably mounted in said bearing and rovided with a clutch member coasting w1th the clutch member of said 'ournal, means for shifting said driven sha t to engage and disengage said clutch members, a driven gear on said driven shaft, a driving shaft rovided with a worm disposed horizontal y below said driven shaft and transversely thereof, a driving rack disposed in an upright position to coact with said driven gear, a crank wheel for driving said rack meshing with said worm, and a supporting roller grooved to receive the rack so that the rack is su ported in driving en agement with tie driven gear and the riven gear may be shifted laterally of the rack to engage and disengage said clutch members.
